"...the law that permitted mandatory retirement in Canada is no longer sustainable..."
It will be interesting to see what the Supreme Court has to say about that. What happens if they decide that it is permissible for a group of employees to collectively and democratically decide they wish to retire at a specific age, like 62, or 55, or 60, or whatever?
Are there any other parts of the collective agreement that could be construed to be discriminatory to identifiable groups?
Perhaps those in the AC "Pay Group" have been unfairly discriminated against? Oh, wait a minute...ahhh, I see...that's not quite the same thing; those are conditions that the pilot group AS A WHOLE have agreed upon, like scheduling rules, GDIP, vacation allotment, pay rates, etc. etc.
Not AT ALL like Age 60 Retirement....hmmm
